SHIJIAZHUANG, China (CNN) -- The former chairwoman of China's Sanlu dairy was sentenced to life in prison and three others received death sentences Thursday in a tainted milk scandal that killed at least six infants and sickened nearly 300,000 others.

Police surround a court building in northern China in late December during the trial.

Tian Wenhua and three other Sanlu Group executives were put on trial for producing and selling fake or substandard products after their arrests in late September.

Tian, who pleaded guilty in December, received a life sentence Thursday. Former deputy general managers Wang Yuliang and Hang Zhiqi received sentences of 15 and eight years, while Wu Jusheng, a former executive heading Sanlu's milk division, was sentenced to five years in prison.

In addition, Sanlu, Tian and Wang were ordered to pay multi-million dollar fines.

The court also sentenced three people to death, including a suspended sentence pending a review, and two others to life in prison. Six more received prison terms of five to 15 years each.

Victims of tainted baby formula are expected to be compensated by the 22 Chinese dairy producers that made the milk.

"The enterprises offered to shoulder the compensation liability," the country's Dairy Industry Association said late last month, according to Xinhua.

"By doing so, they hope to earn understanding and forgiveness of the families of the sickened children."

The group said victims will receive a one-time cash payment, but did not provide the amounts, according to Xinhua.

No date for the payments was given. The dairies also raised money to cover medical bills for any after-effects suffered as a result of the poisoning, the association said.
